    David Blaine - 17 min breath hold

    I don't know if anyone mentioned this?? I didn't read everyone's comments, but you can also hold your breath longer when you're underwater (something with your body's functions knows to start being conservative with oxygen). Same as the water is colder.

    Understanding Spring Lifespan: Insights from a Mechanical Engineering Student

    So currently I'm in school for Mechanical Engineering, though I got a general question. I could have sworn that I read in my physics book working up to the point I am now reading that as long as a spring isn't pushed past it's stress point that it should last forever. Though now I have had...

    Uniform charge across a rod, Professor couldn't answer

    Alright, well I wanted to see what help I could get here, my professor had assigned this problem and when someone in class asked a question, he started doing it on the board and after using ~15min of class time decided there was an issue with the problem. The problem got progressively harder...

    Financial Analysis vs. Computer Science

    Financial Analyst does have it's issues right now, though 3 years down the road no one really knows. In reality though it's hard to find a job with it in the first place as there's long tenure in the field. It really comes down to what's more fun, but computer science let's you do a broad...

    What Speed Range is Safe for a Car on a Wet, Banked Curve?

    Alright, well to help myself out on drawing a free body diagram I made a nominal mass of 1000kg (although I do realize it's possible to do without one). so I got F_N = (1000)(9.8)sin(52.6) = 12900N which in turn the force is the same as F_R which is something I didn't exactly know was meant to...

    What Speed Range is Safe for a Car on a Wet, Banked Curve?

    Homework Statement A curve of radius 60m is banked for a design speed of 100km/h. If the coefficient of static friction is 0.3 (wet pavement), at what range of speeds can a car safely make the curve? v = 100km/hr = 27.8m/s x = ? r = 60m a_r = 12.9m/s² u = 0.3 Homework Equations...
